Features: 1. This Coating Thickness Gauge is used to measure the thickness of the plated and coated sheet on metal, e.g. paint/enamel/ chrome on steel, paint, and anodizing coating on aluminum/copper. 2. The gauge takes the precision integrated probe and uses principles of electromagnetic induction and the eddy current effect, which automatically detects the attribute of substrates. 3. Comes with 6 standard films of different thicknesses, which can calibrate the equipment and reduce errors 4. Using a high-definition display with backlight, the measurement figures are clear at a glance. 5. Widely used in manufacturing industry, metal-processing industry, chemical industry, commodity inspection area, and also able to work steadily in the laboratory, workshop, and outdoor.
